Magnetic Resonance Imaging

Craniocervical MRI findings may include narrowing of the foramen magnum and C1 canal, effacement of the subarachnoid spaces at the cervicomedullary junction, abnormal intrinsic cord signal intensity, and mild to moderate ventriculomegaly. In the spinal canal, associated anomalies such as syringomyelia and changes of myelomalacia are well depicted on MRI. In addition to depicting spinal canal stenosis, MRI also demonstrates disk protrusions and osteophytes that cause compromise (see the image below). ^[7, 8]
